Personally, I would go Brig. I’m not sure how much of that is actually the matchup, and what’s just me being so comfortable playing her, but–
- Brig’s weapon completely bypasses D.Va’s DM, meaning easy damage and whips to proc Inspire. I’m fairly certain that Brig’s Repair Packs also ignore DM. D.Va cannot stop all of Brig’s healing, unlike a lot of other supports
- The armor changes mean D.Va’s weapon got nerfed against Brig’s armor. At the same time, it also means Brig’s weapon against D.Va’s armor was buffed
- Having a personal barrier means you’re very safe from any surprise nukes, and can survive Micro Missiles a bit easier with proper management
- While you’re focused on fighting back, you’re still providing heals for your team thanks to Inspire
- With Rally, you can stun D.Va, interrupt her DM, and make her even more vulnerable. The increased shield size might even allow you to provide a little team protection against her ult
D.Va might be my favorite enemy tank as Brig, honestly
